When I show people pictures of Venus, I get two very common and somewhat perverse questions. OK, I’ll give them a shot:

What is left of the Venera landers today?

Venera-9 style landers were built mostly from titanium and ceramic. So structurally, they are probably still sitting there. Of course, internal electronics (plastic insulations, circuit boards, etc) would be burned up. It is possible that liquid in the large chemical batteries might have boiled and ruptured the main spherical pressure hull, but only if the internal pressure could exceed 100 atmospheres. I’m not sure it could do.

What would happen if I stepped out onto Venus?

Very bad idea. The surface temperature (870 F) is about that of an oven on self-cleaning mode. The high density (1/10th of water) would greatly increase thermal transfer, like a liquid would; however, the atmosphere is still a gas. Supercritical carbon dioxide would not support rapid oxidation (flaming combustion), but it does act as a strong non-polar solvent, sometimes used for dry-cleaning. So I believe it would have the effect of being french-fried in mid air, and quickly reduced to a charcoal figure. A lurid motion-picture special effect waiting to happen. 🙂
